Consider an aqueous solution of CaCl2. The extended Debye-Hckel model can be used to represent the mean ionic activity coefficient and values for the parameters

image text in transcribed Consider an aqueous solution of CaCl2. The extended Debye-Hckel model can be used to represent the mean ionic activity coefficient and values for the parameters are given below. ln=1+I1.178z+zI+0.105I (a) What is the expression with parameter terms for the activity coefficient for water? (b) Plot the ln(xww) as a function of CaCl2 concentration from 0.2 to 5M. (c) What is the freezing point depression of water for the range of concentrations in part b ?
